An all-cellulose composite was prepared from conventional filter paper by converting a selective dissolved fiber surface into a matrix. The structure and mechanical, thermal, and optical properties of this composite were investigated using X-ray diffraction, a scanning electron microscope, an optical microscope, a tensile test, and dynamic viscoelastic(More)
Aims. As part of the DART project we have used the ESO/2.2m Wide Field Imager in conjunction with the VLT/FLAMES ⋆ GIRAFFE spec-trograph to study the detailed properties of the resolved stellar population of the Fornax dwarf spheroidal galaxy out to and beyond its tidal radius. Fornax dSph has had a complicated evolution and contains significant numbers of(More)
We have carried out spectroscopic observations in 4 cluster fields using Subaru's FO-CAS multi-slit spectrograph and obtained spectra for 103 bright disk field and cluster galaxies at 0.06 z 1.20. Seventy-seven of these show emission lines, and 33 provide reasonably-secure determinations of the galaxies' rotation velocity. The rotation velocities,(More)
Optical integrated spectra of bulges have been obtained for 28 spiral galaxies for which the surface brightness prooles were decomposed into disk and bulge contributions by Kent (1985) and Simien & de Vaucouleurs (1986). By applying an appropriate aperture size for each galaxy, the unavoidable contamination of disk starlight has been carefully minimized and(More)
We present a wide field census of resolved stellar populations in the northern half of M81, conducted with Suprime-Cam on the 8-m Subaru telescope and covering an area ∼ 0.3 square degrees. The resulting color-magnitude diagram reaches over one magnitude below the red giant branch (RGB) tip, allowing a detailed comparison between the young and old stellar(More)
We derive age-metallicity relations (AMRs) and orbital parameters for the 1658 solar neighbourhood stars to which accurate distances are measured by the HIPPARCOS satellite. The sample stars comprise 1382 thin disc stars, 229 thick disc stars, and 47 halo stars according to their orbital parameters. We find a considerable scatter for thin disc AMR along the(More)
